* imam HALVQR. QLSEN, oroAK BARK, ILLINOIS, ASSIGNOR TO 'KELLOGG SWITCI-IBOABD AND SUPPLY COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION. or ILLINOIS sooner Application filed December of a socket of the above type for resiliently supporting an audion in order that vibrations and shocks will be absorbed without materially. affecting the elements-of the audion tube.

A feature of my invention'is the provision of a pair of spring. members forming resilient means, bymeans of which the tube supporting member of theisocketis resiliently supported from the base to permit the supporting member to yieldingly vmove in alldirections.

Another feature of "myinvention is the provision of a novel'tube supporting member and spring contact members secured thereto with whichthe prongs of an audion tube areassociated when supported in said supporting member. I

Still another feature of my inventionis the method of associating the resilient means with the supporting member and the method of securing the said resilient means to the base of the socket. 1

The above features of my:inventi0n as well as others not specifically pointed out, will be more fully described in the-ensuing specification... l

For a more complete understanding of my invention reference may be had to the accompanying drawing in which like reference characters in the several views denote like parts, and in which:

which are engaged prongs thereto; I

Fig. 7 is an enlarged fragmentary View :of the base, illustrating one of the methods employed for securing the respective ends of the resilient members to the base of the socket;

Fig. 8 is an enlarged fragmentary view of the base, illustrating an alternate method of securing'the respective ends of the resilient members to the base ofthe socket, and

Fig. 9 is a bottom view of the tube supporting member. Referring now more in detail to the drawings, the socket of my invention-as illustrated comprises a base B of suitable mouldby the terminal pins or ediinsulating' material', having supporting legs 2, on the bottom side thereoffthe said legs 2 being provided with orifices 3 for the reception of screws by means of which the socket base B and its supported parts may be secured to a mounting base or subpanel. 1

The tube socket supporting member -T comprises an inverted cupshaped member 4 provided with four integrally formed downwardly. extending fins or ribs. 5 positioned at right angles to each other and extending below the-rim 6 of the inverted cup'shaped member 4 and the ribs 5 and the wall 7of the same form substantially triangular orifices 8. Spring contacts 9, 10,11 and 12 are secured to the respective faces 13, 14,15 and 16 of the ribs 5 by suitable rivets 17 and the free ends of the springs 9, 10, 11 and 12 ex: tend up into the triangular orifices8. The inverted cup shaped'member 4 is provided withorifices 18 whichare adapted to receive the contact terminal pins or prongs projects ing from the base ofan audlon tubeto engage the free ends of the contact springs 9,10, 11 and 12; A substantially cylindrical member 19 integrally formed with the ribs 5 and depending therefrom is'provided with a threaded stud 20 which is secured thereto during the moulding operation of the member 4 for purposes as will presently be described. Y

Attached to the bottom face of the base B. is a resilient cushion member C comprising a pair of spring membersfll and 22 of suit-' able wire such as spring brass. Each member is formed of two semi-circular loops 23 and 24 and the two members 21 and 22 when positioned on the base B as illustrated form a figure 8. Studs 25 are secured to projecting lugs 26 on the base B, and orifices 27 in therespective studs 25 are adapted to re ceive the depending free ends 28 and 29 of the respective members 21 and 22. The studs 25 are provided with slots 30- which receive the end portions of the respective semi-circular loops 23 and 24 of the members 21 and 22, and by means of a suitable tool the metal adjacent to the slots .30 in the respective studs 25 is burred over to secure the members 21 and 22 againstdisplacement.

The base B is provided with a central orifice 31 which is adapted to loosely receive the projecting ribs 5 of themember T, and when thus positioned the face 32 of the cylindrical portion 19 of the memberd which is provided with a pair of U shaped grooves .33 which are adapted to receive the :U shaped connecting link portions 3d between the semi-circular loops 23 and 2 1 of the respective members 21 and 22. The threaded stud 20 secured to the cylindrical portion 19 rests between the U shaped link portions 34 and a washer 136 and nut 35 which has threaded engagement with the end of the threaded stud 2.0 to secure the tube supporting member T to the resilient member C. The nut 35 in addition to securing the member T to the resilient member C also maintains the U shaped connecting link portions 3 10f the members 21 and 22 in the grooves 33 in the face .32 of the cylindrical portion 19 to prevent the said member T from rotating relative to the base B.

When the prongs of the audion tube are inserted in the orifices 18 in the member T to force them between the free ends of the springs, 9, 10, 11 and 12 and the faces 13, 1 1, 1.5 and 16 of the ribs 5 downward pressure is applied to the tube causing the resilient member 0 to be flexed. The downward movement of the member T is limited as the diameter of the cup member 4 is slightly larger than the central orifice 31 in the base B which permits the rim 6 of the cup member 4 to engage the top face of the base 13 to prevent excessive fiexure of the resilient member C as the tube is inserted; A pair of projecting ears 36 integrally formed with the base 13 lie beneath a portion of the seinicircular portions 23 and 24 of the members 21 and 22 of the resilient member C and when a tube is removed from the tube supporting member T the pull exerted on the tube to remove the same will cause the resilient member C to flex, but this flexure is limited as these projecting ears 36 will be engaged by the semi-circular portions 23 and 24 of the members 21 and 22 which form '22 which form the figure 8 shaped resilient member C produce this cushioning effect and permit'the tube supporting member T to yield slightly toward or away from the base 13 or it vmay oscillate in any direction.

The base is provided on its underside :thereof with four grooves or channels 37,

and at the outer extremity of eachof'these channels 37 are secured terminal members 38 which are secured to the base B by means ofrivets 39, and flexible conductors 4.0 lying within the channels 37 join the contact springs 9, $10, 11 and 12 of the tube supporting member T with the terminals 38. Oneend of each flexible conductor 40:15 soldered to :a tab 41 integrally formed with the terminal 38,1'the other end-of the conductors -41) being in turn soldered to tabs 42 integrally formed with the springs 9, 10,, 11 and 12. "The terminal .members 38 are adapted to receive the external circuit connections and through the medium of'the flexible conductors 40 the circuit is extended to the spring terminals '9, .10, 11 and 12 of the tube supporting member T. With a construction of the type just described the socket is cushioned sand at the same time yieldingly supported for movement in al l directions by a single resilient supporting member. Thus efficient and satisfactory means are provided independent of the resilient supporting means for extending the external electrical circuit to the pins of the tube through the medium of the contact springs ,9, 10, 11 and 12 :of the member 1.

In Fig. 8 I illustrate an alternative method of securing the members 21 ;and22 to the base 13.. The projecting lugs 26 are provided. with suitable orifices 15 which are adapted to receive the depending ends 28 and 29 of members 21 and 22 by means of a force fit.
